SITUIBBIN G DEVICE FOR AUTOMOBILE SPRINGS.

Application filed August 20, 18527.

The objects of the invention are to provide an improvement in snubbing devices for automobile springs.

This device is constructed and arranged for direct attachment to the springs themselves, and serves to prevent violent action from breaking the springs, and to check the abrupt sock of the rebound.

The invention comprises a looped wire, having its side bent at an angle and formed into coils at the angle.

This loop is passed over the springs and is secured thereto by means of a bolt passed through the coils and underneath the springs.

The looped end rests upon the back of the spring and the free extremities are extended forwardly and their extremities are bent laterally to engage with the upper face of the spring. The invention is hereinafter more fully described, illustrated in the accompanying drawings and specifically pointed out in the claims.

In the accompanying drawings; Fig. 1 is a plan of the device; Fig. 2 is a side elevation thereof; Fig. 3 is a plan showing the spring with overlapping free extremities and Fig. 4 is a side elevation thereof.

In these views A is the spring, B the shackle bolt supporting the outer end thereof; C represents the coiled sides of the looped snubbing spring at the angular junction thereof; D is the cross member which closes the loop, and engages with the upper side of the spring A and a bolt 11 is passed through the loops C and underneath the spring A thus holding the spring in place. The free sides E, E, of the loop are passed up the sides of the spring A and are extended transversely over the top of the spring A thus binding the leaves of the spring tightly together.

In Figs. 3 and 4 the extremities overlap and their ends G are turned downwardly and are slidingly movable upon the edges of the spring A, thus locking the snubber spring in place. J represents a turnbuckle employed to extend the sides of a split spring loop.

By the use of this snubber any great amount of separation of the leaves of the spring is prevented, and the leaves will move quietly upon each other and a violent rebound is prevented.

Also by extending the sides the loop can coils,

said composite spring,

Serial No. 214,260.

be adapted to a wider range of sizes of springs.

Having described the invention what I claim as new and desire to secure by Letters Patent is:

1. In a snubber for the flat composite spring of an automobile, a loop comprising resilient steel wire sides bent at similar angles and provided with integral coils in said angles, the looped end of said snubber being engaged with the upper face of said composite spring, a bolt passing through said said. bolt being of sutlicient diameter as to fit snugly within thecoils and to restrain undue contraction of the convolutions thereof, said bolt engaged with the lower face of said composite spring, the free extremities of said snubber being extended laterally over and en aged with the upper side of said composite spring.

2. In a snubber for the flat composite spring of an automobile, a loop comprising resilient steel wire sides bent at similar angles and provided with integral coils in said angles, the looped end of said snubber being engaged with the upper face of said composite spring, a bolt passing through said coils and en aged with the lower face of said composite spring, the free extremities of said snubber being extended laterally over and engaged with the upper side of said composite spring, said laterally extended ex tremities overlapping each other.

-3. In a snubber for the flat composite spring of an automobile, a loop comprising resilient steel wire sides bent at similar angles and provided with integral coils in said angles, the looped end of said snubber being engaged with the upper face of said composite spring, a bolt passing through said coils and engaged with the lower face of said composite spring, the free extremities of said snubber being extended laterally over and engaged with the upper side of said laterally extended extremities overlapping each other, the tips of said overlapping extremities overhanging the edge of said spring.

4. An auxiliary tensioning device for leaf springs and solely carried thereon, comprising a single piece of spring tempered metallic wire bent to form a clip, said clip having a cross arm engaging the top leaf of the spring, a pair of coils joined to each other by the cross arm, a pair of longitudinally extending arms extending from the coils, and hooked over the topmost leaf of the spring, and clamping means to clamp the device on to the spring and adjusting means adapted to adjustably laterally space the longitudinal arms.

5. In a device of the class described, the combination with an automobile chassis frame, a leaf spring, suspension means for said spring, and a resilient spring tensioning element having a portion disposed over the leaves of the spring, a pair of looped portions, a pair of resilient arms extending longitudinal of the spring, said arms having int-urned ends adapted to be snapped over the topmost leaf of the spring, and a transverse rod, said rod having the ends thereof projected between the loops and having an intermediate portion engaging the underside of one of the spring leaves and adjusting means adapted to adjust-ably laterally space the longitudinal arms.

6. In an auxiliary tensioning device for leaf springs comprising a single piece resilient metallic clip, said clip having a trans-- versely disposed arm adapted to engage the top leaf of the spring, a pair of loops joined together by the transverse arm, a pair of longitudinally extending arms extending from the loops, said longitudinal arms having hooked ends disposed over a top leaf, and means for clamping the clip onto the spring and adjusting means adapted to adjustably laterally space the I longitudinal arms.

7. In an auxiliary tension device for leaf springs, comprising a resilient metallic clip, said clip having a transvcrsel y disposed arm adapted to engage the top leaf of the spring, a pair of loops detachably joined together hy the transverse arm, a pair of longitudinal arms having hooked ends disposed over a top leaf, and means for clamping the clip onto the spring.

8. In an auxiliary tension device for leaf v springs, comprising a resilient metallic clip, said clip having a transversely disposed arm adapted to engage the top leaf of the spring, a pair of loops detachably joined together by the transverse arm, a pair of longitudinal arms having hooked ends disposed over a top leaf, and means for clamping the clip onto the spring, said t 'ansversely disposed arm comprising a coupling element, said pair of arms each having a transversely ex tending end making interlocking engagement with. said coupling element.

In testimony whereof I aflix my signature.
